DETAILED DESCRIPTION

Lockers provide individual compartments that may be individually opened and individually secured. Charging lockers are similar but additionally provide one or more sources of power within the locker bays to allow electronic devices contained in the locker bays to be charged while stored therein. Charging lockers may be usefully deployed in environments where individuals may have a need to securely store portable handheld devices, tablet computers, and laptop computers, while the devices receive charging power. Example venues may include schools, airports, malls, restaurants, bars, theatres, amusement parks, and arenas, although virtually any public place may provide a suitable candidate location for a charging locker.

This disclosure is based, at least in part, on the realization that it is desirable to provide a charging locker that is secure, economical to manufacture, and easy to service. In some embodiments, all components of the charging locker other than the frame should be able to be replaced without requiring the charging locker to be removed from where it is installed.

FIG. 1 is a perspective view of a frame 10 of an implementation of a charging locker according to some embodiments. FIG. 2 is an exploded view which shows the frame 10 broken apart into constituent components. As shown in FIGS. 1-2, the frame 10 includes a front support 12, a rear support 14, and four corner transverse pieces 16. The frame 10 also includes a front intermediate vertical support column 18.

In an implementation, the front support 12 includes bars 12A, 12B, 12C, and 12D, that are formed from a single piece of rectangular tubing, e.g. square tubing. The tubing, in this implementation, is notched to form cutout areas and bent at the cutout areas to form miter joints at the corners 15. The miter joints are then welded together, to enable a single piece of tubing to be used to form the front support 12. The rear support 14 includes bars 14A, 14B, 14C, and 14D. In some embodiments, the rear support 14, like the front support 12, is also implemented using a single piece of tubing that has been notched and bent at the cutout areas to form miter joints at the corners 15. The miter joints are then welded together, to enable a single piece of tubing to be used to form the rear support 14.

In an implementation, the corner transverse pieces 16 have ends that are flared to form locating tabs 17 (see FIG. 2) that fit into corresponding slots on front support 12 and rear support 14. The ends of the four corner transverse pieces are respectively welded to the four corresponding corners of the front support 12 and rear support 14. In another implementation, the corner transverse pieces may be fastened to the front and rear supports 12, 14 using mechanical fasteners.

Front intermediate vertical support column 18 has projecting tabs 20 on upper and lower ends. Tabs 20 are received in first corresponding slots 22 on upper horizontal member 12B of front support 12 and second corresponding slots 26 on lower horizontal member 12D of front support 12. The front intermediate vertical support column 18 optionally may be welded to the front support 12 as shown in FIG. 1. The resulting frame, as shown in FIG. 1 is a rectangular box formed with a minimal number of components.

FIG. 3 shows the frame 10 from a lower right front perspective view. As shown in FIG. 3, the frame 10 optionally may be attached to a lower frame 30 of a base cabinet 29 that is constructed similarly to the frame 10. Specifically, in an implementation, lower frame 30 includes a lower front support 32 formed from a single piece of tubing that is notched, bent to form miter joints, and welded. The lower fame 30, in this implementation, also includes a lower rear support 34 formed from a single piece of tubing that is notched, bent to form miter joints, and welded. Lower corner transverse pieces 36 are tabbed and welded to the corners of the lower front support and lower rear support to finish the lower frame into a rectangular solid frame. Although an implementation is shown in FIG. 3 in which lower frame 30 and upper frame 10 are separately formed, in another implementation a single combined upper/lower frame may be formed as a unified frame structure. Likewise, although in some embodiments the front intermediate vertical support column 18 is formed toward the left-hand side of the frame, in other implementations the front intermediate vertical support column 18 may be formed toward the right-hand side of the frame. Thus, while an implementation will be described in which the front intermediate vertical support column 18 is formed toward the left-hand side of the frame, it should be recognized that a mirror image construction is likewise possible and contemplated.

FIG. 4 shows an implementation in which rack mount rails 38 are connected between the transverse pieces 36 of the lower frame 30. The rack mount brackets 38 are joined to the lower frame 30 using fasteners 40 or welds. In one implementation, the lower frame 30 and the rack mount rails 38 are sized to form an EIA rack. The EIA (Electronic Industries Alliance) standard server rack is a 19-inch wide rack enclosure with rack mount rails which are 17¾″ (450.85 mm) apart and whose height is measured in 1.75″ (44.45 mm) unit increments. As shown in FIG. 5, electronic equipment 41 is mounted on the rack mount rails 38 to interconnect the components of the locker system with one or more other locker systems and/or external networks, and to perform power management within the locker system. For example, as shown in FIG. 5, electronic equipment 41 in the form of a multi-port switch may be mounted on the rack mount rails. Similarly, a gateway (not shown) and/or power management system may be mounted on the rack mount rails 38. Other electrical equipment such as a blade server or other computer equipment having mounting hardware conforming with the EIA standard may likewise be mounted on the rack mount rails 38 within lower frame 30. Optionally a base cabinet shelf 39 may be provided to facilitate storage of additional items in the base cabinet 29.

FIG. 6 is a front perspective view of an implementation of a modular shelf unit 42. FIGS. 7 and 8 are rear perspective views of an implementation of a modular shelf unit 42. In the implementation shown in FIGS. 6-8, each modular shelf unit has an open front and an open top, and an integral floor 44, a left side wall 46, a back wall 48, and a right-side wall 50. The integral floor 44, left side wall 46, back wall 48, and right-side wall 50 in one implementation are stamped from a single piece of metal and bent to form the modular shelf unit. Optionally the back corners between the left side wall 46 and back wall 48, and between the right-side wall 50 and back wall 48, may be tack welded together to increase the rigidity of the modular shelf unit.

FIG. 9 is a front perspective view of another implementation of a modular shelf unit 42. In the implementation shown in FIG. 9, each modular shelf unit has an open front, an open top, and an open right side, and an integral floor 44, a left side wall 46, and a back wall 48. The integral floor 44, left side wall 46, and back wall 48 in one implementation are stamped from a single piece of metal and bent to form the modular shelf unit. Optionally the back corners between the left side wall 46 and back wall 48 may be tack welded together to increase the rigidity of the modular shelf unit.

The difference between the implementations shown in FIGS. 6-8 and FIG. 9 is that the shelf unit 42 in FIGS. 6-8 has three walls 46, 48, 50, whereas the implementation shown in FIG. 9 only has two walls 46, 48.

As shown in FIG. 6, in some implementations the side wall designated to separate the interior of the modular shelf unit with a wiring and access compartment 78 is provided with a power/data access window 86. For example, as shown in FIGS. 6-8, the left side wall 46 may be formed shorter than the floor 44 to define the power/data access window 86. Alternatively, as shown in FIG. 9 a cutout region (aperture) may be created in the left side wall 46 to form the power/data access window 86. The power/data access window 86 enables power to be provided within the modular shelf unit 42 as discussed in greater detail below.

Referring to FIGS. 6-8, in one implementation top flanges 52 are provided on each of the left side wall 46, back wall 48, and right-side wall 50. In the implementation such as shown in FIG. 9, top flange 52 is formed on left side wall 46 and back wall 48. Top flanges 52 provide lateral strength to the walls 46, 48, 50, to help prevent deformation of the walls. In an implementation where shelf unit 42 is stamped from a single piece of metal and bent to form the modular shelf unit, the flanges similarly may be formed by being included in the stamp blank and bent as shown in FIGS. 6-8 and 9 when the shelf unit blank is bent to form the shelf unit. Optionally top flanges may be welded together at top left corner 54 and top right corner 56.

Modular shelf units 42 are designed to be stacked on top of each other within the frame 10 of the storage locker such that the lower modular shelf units support the upper modular shelf units. In one implementation, when multiple modular shelf units 42 are stacked on top of each other to form a stack of similarly configured modular shelf units, the top flanges 52 of a lower modular shelf will parallel the floor 44 of an immediately higher modular shelf unit 42 in the stack. In one implementation, the top flanges 52 of a lower modular shelf unit 42 will contact the floor 44 of an immediately higher modular shelf unit 42 in the stack to enable the upper modular shelf unit(s) in the stack to be at least partially supported by the lower modular shelf unit(s).

FIGS. 10-12 show additional details of how the modular shelf units 42 are attached to the frame 10 according to some embodiments. As shown in FIGS. 6-8, in some embodiments the floor 44 of modular shelf unit 42 is shaped to define front right support tab 58, front left support tab 60, and right rear support tab 62. A rear vertical support tab 64 is formed on the left edge of the rear wall to protrude beyond the left side wall 46.

As shown in FIG. 1, in one implementation a first set of notches 66 are formed on the front right interior corner of the front intermediate vertical support column 18. When modular shelf unit 42 is mounted in the frame 10, the front left support tab 60 slides into one of the notches 66 in the front intermediate vertical support column 18 from the front of the intermediate vertical support column 18. A partially transparent view of an example front, left support tab 60 engaged in notch 66 of front intermediate vertical support column 18 is shown in FIG. 10.

A second set of notches 68 are formed in the inside rear corner of the front right vertical bar 12C of front support 12. When modular shelf unit 42 is mounted in the frame 10, the front right support tab 58 slides into one of the notches 68 in the inside rear corner of the front right vertical bar 12C of front support 12. A partially transparent view of an example front-right support tab 58 engaged in notch 68 of front right vertical bar 12C of front support 12 is shown in FIG. 11.

A third set of notches 70 are formed in the inside front corner of the rear right vertical bar 14C of rear support 14. When modular shelf unit 42 is mounted in the frame 10, the rear right support tab 62 slides into one of the notches 70 in the inside front corner of the rear right vertical bar 14C of rear support 14. A partially transparent view of an example rear, right support tab 62 engaged in notch 70 of rear right vertical bar 14C of rear support 14 is shown in FIG. 12.

As described in connection with FIGS. 10-12, the front left tab support 60 slides into notch 66 on intermediate vertical support column 18 from the front, whereas front right support tab 58 and rear right support tab 62 engage notches 68, 70 respectively from inside the frame 10. This allows the modular shelf unit 42 to be inserted into the frame and rotated slightly to cause each of the support tabs to engage its respective notch. Removal of a modular shelf unit 42 may be accomplished by rotating the modular shelf unit 42 slightly to disengage the tabs from the notches, and then extracting the modular shelf unit 42 from the frame 10.

In one implementation, each modular shelf unit is additionally secured to the front right vertical bar 12C of frame 10 using a single fastener such as a machine screw that extends from an interior of the modular shelf unit through aperture 76 and into a corresponding aperture in front right vertical bar 12C. By minimizing the number of fasteners that are required to install a set of modular shelf units into a storage cabinet, it is possible to dramatically reduce the assembly time associated with manufacturing the storage cabinet.

FIG. 13 is a rear perspective view of a storage locker having a stack of similarly configured modular shelf units 42 inserted into frame 10. As shown in FIG. 13, a bracket 74 extends from a top rear frame bar 14B to a bottom rear frame bar 14D. The bracket 74 has a set of slots spaced to receive rear vertical support tabs 64 of the modular shelf units 42 (See FIG. 7). Bracket 74 is attached to rear shelf member, e.g. using two fasteners—one on top and one on bottom. In one implementation, once the set of modular shelf units 42 has been inserted into the frame by securing tabs 58, 60, 62 into notches 66, 68, 70, bracket 74 is installed into locker unit and secured to frame to prevent the modular shelf units from moving relative to frame 10.

FIG. 13 is rear perspective views of an example locker system with a set of modular shelf units installed. As shown in FIG. 13, the modular shelf units extend to the right of the front intermediate vertical support column 18 (when the locker system is viewed from the front). A wiring and access compartment 78 is formed to the left of the front intermediate vertical support column 18. Once the locker system has been installed, if it is necessary to remove one of the modular shelf units from the locker, it is possible to remove the bracket 74 from within the wiring and access compartment 78. The particular modular shelf unit to be removed 42 may then be detached from the frame by unscrewing the fastener extending through aperture 76 (see FIG. 6) that is being used to secure the modular shelf unit 42 to the frame 10. The modular shelf unit may then be removed through the front of the storage locker system and replaced as desired without requiring complete disassembly of the storage locker system and without requiring removal of any other modular shelf unit 42.

By forming each modular shelf unit 42 as a single part that includes the shelf bottom, as well as integral left 46, back 48, and right-side walls 50, it is possible to form locker bays without the use of additional or redundant side panels 92 (See FIGS. 19A & 19B). Specifically, the storage locker system shown in FIGS. 13 and 14 may be installed adjacent a similarly configured storage locker system (see FIGS. 19A-19B) for example by having the vertical portions of the front and rear frames of similarly configured storage locker systems abut. In this installed configuration, side panels 92 are not required on each of the individual storage locker systems, but rather only on ends of the runs, to thereby further reduce manufacturing costs by eliminating duplicative panels. Hence, exterior sheathing panels 92 are only required on units that are freestanding or on ends of runs of adjacent contiguous units.

For example, FIGS. 18A & 18B show a single cabinet charging locker system whereas FIGS. 19A & 19B show a multi-cabinet locker system. As shown in FIGS. 18A &18B, where a single cabinet locker system is provided as a stand-alone deployment, it may be aesthetically advantageous to seal the interior of the locker system using left and right external side panels 92. As shown in FIGS. 19A & 19B, if two or more locker cabinets are deployed side-by-side, it is not necessary to insert additional external side panels 92 between the adjacent cabinets, since aesthetically it does not make any difference and the walls 50 of the modular shelf units prevent access from one locker cabinet to the adjacent locker cabinet. Thus, a cabinet locker system incorporating multiple individual locker cabinets still only requires a single pair of left and right external side panels 92.

FIGS. 15 and 16 show an example locker system with doors 80 providing individual access to storage compartments defined by the modular shelf units 42. As shown in FIGS. 15 and 16, in an implementation the locker system includes a side access door 82 providing secure access to the wiring and access compartment 78. In some implementations, the side access door has one or more key locks to control access to this area. In other implementations, an electronic locking system may be used to provide card access or other digital access to the wiring and access compartment 78.

In an implementation, all wiring associated with providing power and/or data connections to the storage compartments defined by the modular shelf units 42 is routed through the wiring and access compartment 78. The particular configuration of the electrical and data outlets provided within the charging locker will depend on the intended use of the storage compartments. In one implementation, modular electrical and data outlets are provided on a power/data strip 84 that has outlets facing into the storage compartments through power/data access window 86 defined by a cut-away in left side wall 46. In the implementation shown in FIG. 17 the power/data strip 84 incorporates both power/data outlets 88 and electronic locks 90 that are used to secure doors 80. Optionally individual components may be used instead of power/data strips 84 and likewise multiple strips may be provided, e.g. a first strip that contains the power/data outlets 88 and a second strip that mounts the electronic locks 90.

The wiring and access compartment 78 may also be used to store transformers for laptops where the laptops require the use of external electric transformers (bricks). The transformers may be mounted on individual shelves within the wiring and access compartment 78 or otherwise organized for storage within the wiring and access compartment 78. By locating all electrical charging/power supply components, as well as all mechanical components associated with locking the individual compartments within the wiring and access compartment 78, it is possible to perform all necessary maintenance without moving the unit from its installed location. For example, individual locks or sets of locks can be replaced, wiring systems can be changed or replaced, and individual doors can be manually opened and replaced as necessary.

In some embodiments, as shown in FIG. 20, the frame 10 includes a top power strip mounting bar 94 and a lower power strip mounting bar 96. The upper and lower power strip mounting bars 94, 96, are located co-planar with front intermediate vertical support column 18 and define top and bottom interior edges of the wiring and access compartment.

FIGS. 21-22 show an example power strip 98, in which FIG. 21 is a left side view of the power strip 98 and FIG. 22 is a front view of the power strip 98. FIGS. 23-25 show several additional example power strips with different types of power connectors. The example interchangeable power strips 98 shown in FIGS. 21-25 are designed to be secured within wiring and access compartment 78 to top power strip mounting bar 94 and bottom power strip mounting bar 96. In some embodiments, as shown in FIG. 21, the power strip 98 has a top hook 100 formed on a front surface 104 and has a plurality of electrical receptacles 102 also formed on the front surface 104. The top hook 100 is designed to fit into one of several slots 106 cut into a top surface of the top power strip mounting bar 94. When the power strip 98 is suspended by top hook 100 in one of the slots 106 toward the front of the locker cabinet, the electrical receptacles 102 are spaced such that one of the electrical receptacles 102 is accessible through a respective one of the power/data access windows 86 of each modular shelf unit 42. The power strip 98 may be secured to the bottom power strip mounting bar 96 using a mechanical fastener such as a machine screw.

In some embodiments, multiple power strips 98 may be secured to have different types of electrical receptacles 102 accessible through power/data access window 86. In some embodiments, three slots 106 are formed on top power strip mounting bar 94 in the region above power/data access window 86 to allow up to three power strips 98 to be retained within the wiring and access compartment 78 such that three electrical receptacles 102 are able to be accessed from within each modular shelf unit 42.

FIGS. 22-25 show example power strips 98 with different types of electrical receptacles 102. For example, FIG. 22 shows an example power strip with electrical receptacles 102 formed as USB ports. FIG. 23 shows an example power strip with electrical receptacles 102 formed on the ends of whips 108. FIG. 24 shows an example power strip with electrical receptacles 102 formed as barrel jacks. FIG. 25 shows an example power strip with electrical receptacles 102 formed as NEMA outlets. Power strips 98 may be provided with numerous other types of power outlets as well, depending on the type of power required by devices to be stored in the locker. Likewise, although each power strip 98 is shown as having a single electrical receptacle 102 for a given modular shelf unit 42, in some embodiments a given power strip may provide multiple electrical receptacles 102 at each modular shelf unit 42.

In some locker system installations, it may be desirable to provide a first type of electrical receptacle 102 in the interior of each modular shelf unit 42, whereas in other locker system installations it may be desirable to provide another type of electrical receptacle 102 in the interior of each modular shelf unit 42. By making the power strips 98 modular and interchangeable, and securable within the wiring and access compartment using a simple top hook 100 and single mechanical fastener, it is possible to quickly and easily customize the locker system installation to provide the desired type of electrical receptacles 102 within the modular shelf units 42. Likewise, it becomes possible to quickly and easily change the type of electrical receptacle 102 provided within the bays of the locker system by switching power strips 98 on installed locker systems.

As noted above, in some embodiments several slots 106 (such as three slots) are formed on top power strip mounting bar 94 in the region above power/data access window 86 to allow several electrical receptacles 102 to be presented for access within each modular shelf unit 42. If a given installation does not require use of the same number of power strips 98 as there are slots 106, a filler panel 108 may be used to cover portions of the power/data access window 86 to prevent access from the interior of the modular shelf units to the interior of the wiring and access compartment.

FIGS. 26-28 show several example filler panels 108, in which FIG. 26 is a side view of an example filler panel 108 and FIGS. 27-28 show front views of two example filler panels 108. As shown in FIG. 26, in some embodiments the filler panel 108 includes a top hook 100 that is configured in the same manner as the top hook 100 of power strip 98. Thus, the filler panel 108 may be secured to the top power strip mounting bar 94 and to the bottom power strip mounting bar 96 in the same manner as power strip 98. As shown in FIGS. 27 and 28, the filler panel 108 may be the same width as a power strip 98 (FIG. 27) or optionally may be twice as wide as a power strip 98 (FIG. 28). Where the filler panel 108 is twice as wide as a power strip 98, the filler panel 108 may incorporate multiple top hooks 100 to engage multiple slots 106 in top power strip mounting bar.

Although an implementation was shown in which the wiring and access area 78 was formed to the left of the modular shelf units, it should be understood that the design shown in the several figures and described herein could be implemented by using mirror images of the frame 10 and modular shelf units 42 to cause the wiring and access compartment 78 to be formed to the right of the modular shelf units.

Although an implementation has been shown in the figures in which ten similar charging lockers are shown together forming a single storage system, in other implementations fewer or greater numbers of similar charging lockers may be included in a storage system. Likewise, it should be understood that multiple similar charging lockers may be placed side by side to form a larger bank of charging lockers which may be individually or collectively controlled.
